The incident is currently being labeled as a Class A mishap, according to Military.com, which first reported on the incident. Those are defined as having fatality or permanent total disability and/or “$2 million or more in damage and/or aircraft destroyed,” a post on the Naval Safety Center’s website says.

According to a Naval Safety Center report updated March 10th, the Marines have had four aviation class A mishaps this fiscal year, including a night training flight collision of two U.S. Marine CH-53 Super Stallions in Hawaii in January that killed 12 Marines.

Previous incidents have led to questions about whether budget cuts are endangering troops by forcing cuts in maintenance and training.

The fire on the Kearsarge is currently under investigation, McConnaughey said.

Harriers generally provide sorties in support of the air campaign against the Islamic State in Iraq and Syria.

Flight operations supporting Operation Inherent Resolve resumed soon after the incident, McConnaughey said, and the Kearsarge continues to support missions in the 5th Fleet area of operations.
